Simple, Novel Process for Isolating Cannabinoids from Complex Crude Hemp Extracts to Replace Winterisation and Other Energy Intensive Processes

Published: Feb 05, 2023   

The current industrial process to purify CBD from C. sativa extracts is long and intensive, requiring several steps such as winterification for 48 hours at -45 C and high-temperature, high vacuum distillation. These processes are capital-intensive and generate large amounts of toxic solvent waste. In contrast, the methodology proposed herein could change the way CBD is obtained, doing so in a single step that is fast and reusable. Furthermore, the new process is simple and easily implemented and does not require any intensive operator training.
